The authors assessed the effects of resistance training and walking exercise on measures of functional fitness. Sixty-four volunteers (average age 83.5 years) from an independent-living facility were randomly assigned to walking, resistance training, or control groups. Participants in the walking and resistance-training groups engaged in two exercise sessions per week for 16 weeks. Measures of functional fitness included upper and lower body strength, hip and shoulder flexibility, agility and balance, coordination, blood pressure, and resting heart rate. Repeated measures analysis of variance was used to examine pretest to posttest differences. Both exercise groups showed significant improvements relative to control group in upper and lower body strength, shoulder flexibility, and agility and balance exercise. Findings demonstrate that exercise can lead to improvements in multiple domains of functional fitness even among very old, previously sedentary individuals, possibly making activities of daily living easier to perform.
作者评估了阻力训练和步行锻炼对功能性健身指标的影响。来自一个独立生活设施的64名志愿者（平均年龄83.5岁）被随机分配到步行组、阻力训练组或对照组。步行组和阻力训练组的参与者每周进行两次锻炼，持续16周。功能性健身指标包括上下肢力量、髋部和肩部灵活性、敏捷性和平衡能力、协调性、血压和静息心率。采用重复测量方差分析来检验测试前到测试后的差异。两个锻炼组相对于对照组在上肢和下肢力量、肩部灵活性以及敏捷性和平衡锻炼方面均有显著改善。研究结果表明，即使在非常年老、以前久坐不动的个体中，锻炼也能使功能性健身的多个方面得到改善，可能会使日常生活活动更易于进行。
